About this tool
Principal & interest is calculated with the standard amortization formula: M = P × [r(1+r)ⁿ] / [(1+r)ⁿ − 1], where P is the loan amount, r is the monthly interest rate, and n is the number of monthly payments. Property tax, homeowner's insurance, PMI, and HOA fees are optional and added on top as flat monthly amounts.
The Amortization tab shows how much of each year's payments goes toward principal versus interest, and your remaining loan balance. Early payments are mostly interest, and that shifts toward principal as the loan matures.
